Turbomachinery Generative Design & Optimization
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Enteknograte’s engineering team optimizes complex geometries with respect to given targets, such as total pressure loss and velocity uniformity with use of advanced simulation tools such as Star-ccm+, Ansys Fluent and Numeca Fine/Turbo. It does so by computing the sensitivities of the geometry itself versus those targets and then modifying it.
The sensitivity information comes directly from the flow field so the optimized shape is the one that fits the given flow best. Unlike traditional design methods that rely on trial and error between a given geometry and flow field predicted by CFD codes, we use 3D inverse design method starts by identifying what we want to do to the fluid flow in terms of 3D pressure field and mathematically derives the optimal geometry to achieve that outcome. This significantly reduces the time taken for each design.

CFD Analysis of Propulsion Systems and Cavitation for Marine and Shipbuilding Industry
For water pumps, marine propellers, and other equipment involving hydrofoils, cavitation can cause problems such as vibration, increased hydrodynamic drag, pressure pulsation, noise, and erosion on solid surfaces. Most of these problems are related to the transient behavior of cavitation structures.

Machine learning is a method of data analysis that automates analytical model building. It is a branch of Artificial Intelligence based on the idea that systems can learn from data, identify patterns and make decisions with minimal human intervention. With Artificial Intelligence (AI) applications in CAE, that is Mechanical Engineering and FEA and CFD Simulations as design tools, our CAE engineers evaluate the possible changes (and limits) coming from Machine learning, whether Deep Learning (DL), or Support vector machine (SVM) or even Genetic algorithms to specify definitive influence in some optimization problems and the solution of complex systems.

Structural vibration can be a source for many product related problems; it can cause fatigue and durability problems as well as adverse reactions to the user or bystanders in the form of undesirable vibrations that can be felt or heard. As well, undesired structural vibrations can prevent products from operating as required and potentially becoming a safety concern. The Vibration Fatigue simulation predict fatigue in the frequency domain and it is more realistic and efficient than time-domain analysis for many applications with random loading such as wind and wave loads.
